Descriptions

Measles, mumps, and rubella virus vaccine live is an active immunizing agent used to prevent infection by the measles, mumps, and rubella viruses. It works by causing your body to produce its own protection (antibodies) against the virus.

Measles (also known as coughing measles, hard measles, morbilli, red measles, rubeola, and 10-day measles) is an infection that is easily spread from one person to another. Infection with measles can cause serious problems, such as stomach problems, pneumonia, ear infections, sinus problems, convulsions (seizures), brain damage, and possibly death. The risk of serious complications and death is greater for adults and infants than for children and teenagers.

Mumps is an infection that can cause serious problems, such as encephalitis and meningitis, which affect the brain. In addition, adolescent boys and men are very susceptible to a condition called orchitis, which causes pain and swelling in the testicles and scrotum and, in rare cases, sterility. Also, mumps infection can cause spontaneous abortion (miscarriage) in women during the first 3 months of pregnancy.

Rubella (also known as German measles) is a serious infection that causes miscarriages, stillbirths, or birth defects in unborn babies when pregnant women get the disease.

While immunization against measles, mumps, and rubella is recommended for all persons 12 months of age and older, it is especially important for women of childbearing age and persons traveling outside the U.S.

If measles, mumps, and rubella vaccine is to be given to a child, the child should be at least 12 months of age. This is to make sure the measles vaccine is effective. In a younger child, antibodies from the mother may interfere with the effectiveness of the vaccine.

This vaccine should be administered only by or under the supervision of your doctor or other health care professional.
